Embodiment Construction
[0016] Such as figure 1 As shown, the present invention comprises a tubular outer wall 1 and a cylindrical inner hole 2 surrounded by the tubular outer wall 1. The tubular outer wall 1 is provided with a step 3 matching with the cylinder mouth, and the outer end of the cylindrical inner hole 2 is provided with a conical inverted corner 4.
[0017] The cylindrical inner hole 2 and the chamfer 4 of the outer end of the cylindrical inner hole 2 are transitioned through a rounded corner 5 . The diameter of cylindrical inner hole 2 is the same as the inner diameter of the cylinder barrel of the assembled oil cylinder, and the larger clearance fit is convenient for assembly, and the length is connected with the inner diameter of the assembled oil cylinder. The chamfer 4 is less than or equal to 15°, and the length of the chamfer is appropriately longer to facilitate assembly and at least make the large opening larger than the outer diameter of the piston seal to be assembled. The ...

The invention discloses an oil cylinder seal assembly guide device, in particular relates to a guide device for assembling an oil cylinder piston seal with a cylinder barrel. The technical problem to be solved is difficult assembly or easy damage of the seal in the assembly of the piston seal and the cylinder barrel. The oil cylinder seal assembly guide device comprises a tubular outer wall, and a cylindrical inner hole surrounded by the tubular outer wall, wherein a step fitting a cylinder opening of an oil cylinder is arranged on the tubular outer wall; and a conical chamfer is arranged at the outer end of the cylindrical inner hole. After the oil cylinder seal assembly guide device uses the structure, the piston seal is smoothly assembled in the cylinder barrel to prevent edges of the cylinder barrel from damaging the seal, so that the product quality and the production efficiency of hydraulic oil cylinders are improved.
Description
technical field [0001] The invention relates to a hydraulic oil cylinder assembly device, in particular to a guide device for assembling the oil cylinder piston seal and cylinder barrel. Background technique [0002] When the piston seal is assembled with the cylinder, especially for large workpieces, it is difficult to install or easily damage the seal without special equipment to align the two; The difference between the small diameter of the thread and the inner diameter of the cylinder is small, but there is a large elastic interference in the seal, which leads to seal damage. Solving this assembly problem is of great significance for improving the product quality and production efficiency of hydraulic cylinders. Contents of the invention [0003] The technical problem to be solved by the present invention is that when the piston seal is assembled with the cylinder, it is difficult to install or easily damage the seal, and to provide an oil cylinder seal assembly guid...
